[18:54:44] <Jymmm> rue_house: Do you have any links for info on reburners (gassifiers)? I'm thinking of making my own variety of an (outoodr?) wood stove and I'm thinking pipe as an air channel to a pipe with holes (jets) in it, but not sure if that's the right/better approach or not.
[18:55:29] <Jymmm> rue_house: maybe a vertical 55gal drum stove
[18:57:27] <Jymmm> aybe a varieant on a bullerjan, but I can't find data on convection stove like that. performance, drawbacks, etc
[18:57:34] <Jymmm> maybe*
[19:19:40] <rue_house> I'm using hot water tank and the metal closest to the file lasts about a year
[19:54:57] <Jymmm> I haven't been able to find old hot water tanks. What are you using inside the house for a radiant source?
[19:55:17] <Jymmm> pex tubing? car radiatorand fan?

[20:18:13] <rue_shop3> hey
[20:18:33] <rue_shop3> I put a car radiator in the air duct
[20:19:05] <rue_shop3> those images were for the heat collector, but its the same idea
[20:19:06] <Jymmm> rue_house: and that serves for the WHOLE house? in the winter?
[20:19:17] <rue_shop3> bit weak but yea
[20:19:27] <Jymmm> need a bigger radiator?
[20:19:32] <rue_shop3> yea
[20:19:38] <rue_shop3> but cant add anymore backpressure
[20:19:51] <rue_shop3> so I need to add another rad and split up the air flow
[20:19:58] <Jymmm> about what temp is the inlet of the radiator?
[20:20:24] <Jymmm> water temp that is
[20:20:39] <Jymmm> well, inpet and outlet temps I guess
[20:20:43] <Jymmm> inlet*
[20:25:42] <rue_shop3> its designed for 80c
[20:26:07] <rue_shop3> its a 2.3L caravan radiator, its not big enough
[20:26:22] <rue_shop3> but I cant find ANY specs on ANY radiators for cars
[20:26:40] <rue_shop3> its like the industry wants to coverup how much gas you dump into heating the planet
[20:26:41] <Jymmm> heh, I understand that.
[20:27:01] <Jymmm> I was more curious on the effeciance of the radiator
[20:27:15] <Jymmm> 180f in, 100F out, etc
[20:28:02] <rue_shop3> I had the flow and temp diff data around
[20:28:15] <rue_shop3> iirc, I'm getting about 8000 btu/hr?
[20:28:22] <Jymmm> ah, ok
[20:28:38] <Jymmm> kind low,is that due to the physical size of the rad?
[20:29:24] <rue_house> must be wrong number the gas furnace is 67000btu/hr and its about 70% of that
[20:29:27] <Jymmm> I calculated my uninsulated garage needing 36K btu/hr, so my lil 4k/90 btu heater aint gonna cut it =)
[20:29:51] <Jymmm> 47T btu
[20:29:56] <Jymmm> 47K btu
[20:30:09] <rue_shop3> the boiler itself puts out about 4x that,
[20:30:18] <Jymmm> 67000 * .70 = 47000
[20:30:21] <rue_shop3> its often sitting idle waiting for hte water temp to come down
[20:30:30] <rue_shop3> the boiler was designed for 1Mbtu/hr
[20:30:44] <Jymmm> yeow
[20:30:45] <rue_shop3> it didn't scale as well as I thought
[20:30:59] <Jymmm> whats the avg coldest?
[20:31:11] <rue_shop3> and its good, at that rate I'd be shoveling fuel in really fast trying to keep it going
[20:31:15] <rue_shop3> dunno
[20:31:16] <Jymmm> outdoor temp that is
[20:31:31] <rue_shop3> I can give you sql data for temp by the minute for the last 5 years
[20:31:34] <Jymmm> or, how cold does it get in the winter there?
[20:31:46] <rue_shop3> it can get down to -10c for a bit sometimes
[20:31:55] <rue_shop3> dosn't stay that cold for long
[20:32:15] <rue_shop3> somewhere between 2c and -3c
[20:32:46] <Jymmm> Here, the winter coldest average is 28F / -2c
[20:33:40] <Jymmm> I'm looking at a 30F rise, and would be awesoe for a 35-40F rise. 72F optimal
[20:34:28] <Jymmm> I am even considereing the bullerkjan design,
[20:34:49] <Jymmm> or a double barrel stove, with one barrel inside, and the other with firebox outside
[20:35:11] <Jymmm> I REALLY dont want a firebox in the garage
[20:35:57] <Jymmm> https://www.youtube.com/watch?v=IBMSDp5puEE barrel stove /radiator setup =)
[20:40:49] <rue_shop3> cambam cant get the pofile right, its choosing the wrong side of some of the lines
[20:41:14] <rue_shop3> this is what I'm currently occupied with
[20:41:24] <rue_shop3> I may need to write my own cam software
[20:41:47] <rue_shop3> partly because nobody understands taking a 2d file and turning it into an nc file
[20:46:59] <Jymmm> There is DXF2gcode
[20:47:23] <Jymmm> Are you doing anything to capture/use the wood gasses?
[20:51:34] <rue_shop3> its a multistage burner
[20:51:59] <Tom_L> rue_shop3
[20:52:07] <Tom_L> ready to try some software?
[20:52:33] <rue_shop3> it would be nice to have something that works right
[20:52:42] <rue_shop3> I'm gonna have to go back to writing my own
[20:52:49] <Tom_L> i'm trying to figure out how to get this to an iso
[20:52:55] <Tom_L> i think just the files would work though
[20:53:23] <Tom_L> let me try something..
[20:54:38] <Tom_L> it takes a bit of setup but i can help with that
[20:54:54] <Tom_L> got time tonight?
[20:57:18] <Tom_L> rar file ok?
[21:02:46] <Tom_L> rue_shop3!!!
[21:24:00] <rue_shop3> sorry pretymuh slipped off to sleep like 3 itmes
[21:26:24] <Tom_L> you get the pm
[22:29:41] <katsmeow> .
[22:30:08] <rue_house> there you are
[22:30:18] <katsmeow> i been here
[22:30:30] <rue_house> havn't seen you much latley
[22:30:47] <rue_house> I think you left before I finished talking to ya last time
[22:31:00] <katsmeow> days ago?
[22:31:01] <rue_house> nowonder the walls know so much
[22:31:03] <rue_house> yea
[22:31:41] <rue_house> <rue_house> steeeeel
[22:31:42] <rue_house> <rue_house> I dont think its hardened
[22:31:42] <rue_house> <rue_house> like, 5 feet
[22:31:42] <rue_house> <rue_house> so, enough... she;s not here
[22:32:09] <rue_house> I'm caught up in trying to get a cnc machine running
[22:32:52] <katsmeow> o
[22:33:11] <katsmeow> so a year or so?
[22:34:31] <rue_house> oh your so pesemistic
[22:34:45] <katsmeow> yeas
[22:34:52] <rue_house> and your right about autodesk, all 64 bit
[22:35:03] <rue_house> even for linux, needs 64 bit
[22:35:14] <katsmeow> :-(
[22:36:40] <rue_house> do you have, stashed away, any old CAM software?
[22:36:43] <rue_house> dos even?
[22:36:47] <rue_house> anything?
[22:37:52] <katsmeow> nope
[22:38:20] <rue_house> I'm gonna be balistic on this project till I can convert a dxf to an NC file
[22:38:32] <rue_house> I'M HAVING TO WRITE A CAM PROGRAM
[22:38:42] <katsmeow> so a year or so?
[22:38:47] <rue_house> no
[22:39:04] <rue_house> I have to finish it soon or what its for will vaporize
[22:39:17] <rue_house> at which time I background the current tasks and work on the other thigns
[22:39:38] <rue_house> if the BAMCAM worked, I'd have prolly made another thing for ya tonight :/
[22:40:03] <katsmeow> the what?
[22:40:09] <rue_house> but bamcam cant figure out what side of the lines its supposed to be on to profile a square
[22:40:21] <rue_house> so half the lines are cut on the inside and half on the outside
[22:41:00] <katsmeow> add a taper to the outside of .00001secs
[22:41:50] <rue_house> hu?
[22:42:24] <rue_house> the only softwar I can find to do CAM cant understand what sides of the lines to cut
[22:42:58] <katsmeow> i am telling you some will regognise the outside if it is to be cut at an angle
[22:43:12] <katsmeow> just make the angle too small to set up the machine to cut it
[22:43:44] <rue_house> its a complex peice, and its got half of the 74 segments backwards
[22:43:47] <katsmeow> ymmv
[22:43:59] <katsmeow> you didn't hear my typing
[22:44:10] <rue_house> there is a library called ....
[22:44:16] <rue_house> https://sourceforge.net/projects/polyclipping/files/
[22:44:31] <rue_house> clipper, its what 3d printers use to work out which side of the line to cut on
[22:44:38] <rue_house> I'm trying to understand it now
[22:47:03] <rue_house> oh god, this can do the pocketing calcs too
[22:48:03] <rue_house> aaaaaah, all I need is this library
[22:52:17] <rue_house> the only bad limit is that it cant do curves
[23:29:56] <katsmeow> http://www.ebay.com/itm/300727473486 <<== for *very* low circuit loading and 500v/div on the scope
[23:33:41] * katsmeow looks at http://www.ebay.com/itm/310126661555
[23:35:35] <rue_house> oh this is frustrating, the capable code parts area spread over a bunch of languages
[23:40:10] <katsmeow> DC 12V 70W Motor Electric High Pressure Diaphragm Water Self Priming Pump 6L/Min
[23:40:26] <katsmeow> blow cooling pil on your machinery
[23:40:33] <katsmeow> Oil, not pil
[23:42:31] <rue_house> I wonder if the seals are ok for oil
[23:42:39] <rue_house> 70W?
[23:42:47] <rue_house> thats a lot of cooling
[23:44:08] <katsmeow> ~gallon/minute ; 4L/minute
[23:44:19] <katsmeow> i dunno what math they use
[23:49:43] <rue_house> int n = Calc::get_fragments_from_r(radius, fn, fs, fa);
[23:49:54] <rue_house> the library only works with line segemnts
[23:50:03] <rue_house> so it converts circles to line segments
[23:50:36] <rue_house> based on either number_of_segments, segment_size, or segment_angle
[23:50:58] <katsmeow> k
[23:51:43] <rue_house> int Calc::get_fragments_from_r(double r, double fn, double fs, double fa)
[23:51:44] <rue_house> {
[23:51:44] <rue_house> if (r < GRID_FINE) return 3;
[23:51:44] <rue_house> if (fn > 0.0) return (int)(fn >= 3 ? fn : 3);
[23:51:44] <rue_house> return (int)ceil(fmax(fmin(360.0 / fa, r*2*M_PI / fs), 5));
[23:51:44] <rue_house> }
